To ALL WHoM 1T MAY coNcERN: n

Be it known that I, WILLIAM FALLON, of the city of Washington, District of Columbia, have invented a new and improved Mode of an -Extension File-Binder; vand I-do hereby declare that the following is afull and exact description thereof, reference being had to the accompanying drawings, and"to the letters of reference The nature of my invention consists in the use of a folding extension on the back' of the said folding extension file-binder, as shown at A, vand in combination with a flap in front, B, and the India-rubber strap, D, and clasp E, for the purpose of securing any given number of papers or documents; the back to consist of a plane surface,.with. the superfluous material in said back laid in, in a fold or folds made of any flexible material, cloth or leather, such asis used in the ordinary book-binding business. The flap B in front folding over and en top of package inside of upper cover C,V the India-rubber strap D made with a reinforce at each end, and a.

hole punched in one end to slip o 'ver the clasp E; the other end, back of reinforce, embraced by the piece F, so as to t in the clasp E-when drawn around the package, as shown on iig. 1. The clasp E is perforated with two holes at an equal distance from centre, and the upper sidezof cover G perforated in a corresponding manner, and the clasp E tied on with tape or cord, as shown on the inside of cover C, marked 2.

Figurel is the extension {ile-binder in use.

Figure 6 is the same before bending.

Figure 'Tris the clasp punched with holes and bent ready to be tied on file-binder.

Figure 8 is the samebefore bending. y

To enable others skilled in the art to make and use my invention, Iwill proceed to describe its construction and operation. v

I construct my extension file-binder of the desired size, two sides, upper and under, ofpasteboard or other material answering the same purpose. To those I fix in the ordinary book-bindingV way the back, made of cloth, leather, or any flexible material of the size to form the back covering for the largest package of papers or doc uments I'have to enclose, having it made forvthe largest. I fold part of the back in on the in and under side, thereby leaving enough of back for the smallest package, leaving the back with a smooth, plane surface. I make the flap to cover the frontof the package, and tix it in the ordinary way to the front of the under side of .file-binder. This is for the purpose of protecting the package in front by completely covering it in said' place. I construct my India-rubber strapwith a reinforce at each end, to pass over the clasp fixed on the upper side of file-binder. i I envelope the strap close up to the reinforce on the opposite end from where it is tied on binder with a'piece of tin or other metallic substance. The reinforce on this end is to prevent the rubber strap from slipping through when the tension is'on. The reinforce on the other end is to give additional strengthat button-hole." I make my clasp of tin, `or other metallic substance answering the same purpose, in the form and shape given in the accompanying drawing, marked E. I adjust it to upper side of file-binder by means of tape or cord passing through holes punched through cover and clasp in a corresponding manner, tying it loosely, so as to leave room enough for the rubber band to lie between the cover and the clasp.

vWhat I claim as my invention, and desire to secure by Letters Patent, is-.-

- The combination of a folding-extension back to {ile-binders, with flap in front, and India-rubber strap, with reinforce on each end, and clasps for same, as described herein.
